The original suction head rotating at intervals of backwashing time is changed into the suction head attached to the two sides of the filter screen plate, the cleaning range of the suction head completely covers the filter cloth, and the cleaning is more thorough without dead angles. The equipment with the same performance, the stacked self-cleaning sucking filter provided by the invention, has larger filtering area and treatment water quantity, can be manufactured in a modularized and overlapped mode, and is easier to expand and maintain.
Description
Technical Field
The invention relates to a laminated self-cleaning filter with a brand new structure, which is suitable for removing suspended matters and particles in water bodies, reducing turbidity, purifying water quality, reducing the generation of system dirt, bacteria, algae, rust and the like in industry, municipal administration and agriculture so as to purify water quality and protect other equipment of a system to normally work, and belongs to the field of water treatment and filtration.
Background
In the existing self-cleaning filter, a filter component is a filter cylinder in the middle, raw water enters the interior of the filter cylinder from a water inlet and flows out from a water outlet after being filtered by the filter cylinder. Along with the impurity is intercepted in straining a section of thick bamboo, the pressure differential of water inlet and delivery port changes, when reaching preset differential pressure value or preset time, the backwash process starts, and external motor drives and sucks the scanner rotation, and the impurity of straining a section of thick bamboo inner wall is sucked by sucking the scanner and is discharged through the blowoff valve.
The self-cleaning sucking washing filter component with the structure is a hollow filter cylinder made of a filter screen, and the water inlet and outlet modes are water inlet and water outlet inside the filter cylinder. Therefore, the following disadvantages exist:
1. cylindrical filter assembly, the filter area is limited by the volume of the device.
2. Raw water is filtered through the interior of the filter cylinder and flows to the exterior of the filter cylinder, impurities are trapped in the filter cylinder, and once the filter cylinder is blocked, the filter cylinder is not easy to clean.
3. Sucking scanners are distributed at intervals, so that cleaning dead corners can occur, and a filter screen cannot be thoroughly cleaned.
Disclosure of Invention
The invention aims to provide a laminated self-cleaning sucking filter with a brand new structure, which improves the structure of the existing self-cleaning sucking filtering component, so that the filtering area of the self-cleaning sucking filter is larger, the operation process is more stable, the cleaning is more thorough, and the maintenance is easier.
The invention provides a stacked self-cleaning sucking filter for filtering and intercepting impurities in water, which comprises a filter screen plate, a filter frame plate, a water inlet branch, a water inlet pipe, a water inlet, a central sewage discharge pipe, a water outlet pipe, a water outlet branch, a sucking head, a pressure switch, a backwashing valve and an electric control device. Each filters on the deckle board and filters the otter board on have branch mouth of a river and branch mouth of a river respectively, and N filters the deckle board and filters the otter board interval and install into a cylinder, divides the mouth of a river and divides the mouth of a river to connect inlet tube and outlet pipe respectively, and the cylinder center of filtering deckle board and filter the otter board and forming is installed to central blow off pipe, and suction head connection central blow off pipe is installed in filtering the deckle board, and the drain is installed in central blow off pipe one end, and electrically controlled device and pressure switch install on the cylinder.
The two surfaces of the filter screen plate are covered with flat filter cloth, and the filter cloth is made of metal, fiber or ceramic.
The laminated self-cleaning sucking filter has the advantages that the filtering cavity and the filtering component are formed by laminating the filtering frame plate and the filtering screen plate, the filtering component is changed into N hollow filtering screen plates from the original filtering cylinder, and the filtering area and the treated water quantity are greatly increased. The original rotary suction head at the backwashing time interval is changed into the suction head stuck on the two sides of the filter screen plate, the cleaning range of the suction head completely covers the filter cloth, and the cleaning is more thorough without dead angles. The equipment with the same performance, the stacked self-cleaning sucking filter provided by the invention, has larger filtering area and treatment water quantity, can be manufactured in a modularized and overlapped mode, and is easier to expand and maintain.
Drawings
Fig. 1 is a schematic diagram of the present invention in a stacked self-cleaning suction filter configuration.
Detailed Description
The invention provides a stacked self-cleaning sucking filter for filtering and intercepting impurities in water, which comprises a filter screen plate 1, a filter frame plate 2, a water inlet separating port 3, a water inlet pipe 4, a water inlet 5, a central sewage discharge pipe 6, a water outlet 7, a water outlet pipe 8, a water outlet separating port 9, a sucking head 10, a pressure switch, a backwashing valve and an electric control device. Each filters on the framed panel 2 and filters respectively on otter board 1 and has divide the mouth of a river 3 and divide the mouth of a river 9, N filters framed panel 2 and filters 1 interval installation of otter board and become a cylinder, divide the mouth of a river 3 and divide the mouth of a river 9 respectively and connect inlet tube 4 and outlet pipe 8, central blow off pipe 10 is installed at the cylinder center of filtering framed panel 2 and filtering otter board 1 constitution, suction head 10 is connected central blow off pipe and is installed in filtering framed panel 2, the drain is installed in central blow off pipe one end, electrically controlled device and pressure switch install on the cylinder.
The two surfaces of the filter screen plate are covered with flat filter media, and the filter media are made of metal, fiber or ceramic.
The working process and the working principle of the invention are as follows: as shown in the schematic structural diagram of fig. 1, raw water to be filtered enters a water inlet pipe 4 from a water inlet 5, the raw water flows into a filtering frame plate 2 through a water dividing inlet 3, the raw water enters a filtering screen plate 1 after being filtered by a filtering medium on the filtering screen plate 1 by pressure in a pipeline, and the filtered water flows into a water outlet pipe 8 through a water dividing outlet 9 and then flows out of a water outlet 7. Along with the continuous progress of filtration process, impurity in the raw water is held back on the filter media who covers filter screen 1, filter media filtration efficiency reduces gradually, when the pressure differential of inlet outlet reaches the default or when presetting the time, automatic control device starts the self-cleaning process, the blowoff valve is opened, outside drive arrangement drives central authorities 'blow off pipe 6 rotatory, along with the rotation of central authorities' blow off pipe 6, suction head 10 uses central authorities 'blow off pipe 6 to do circular motion as the centre of a circle, inhale impurity on the filter media in the central authorities' blow off pipe 6, wash filter media. When the pressure difference of the water inlet and the water outlet returns to the preset value or the preset time, the self-cleaning process is stopped, the whole filtering and cleaning process is continuously carried out, and water is discharged continuously.
